Division 1.1

The lower legform impactor shall consist of two foam-covered rigid segments, representing femur (upper leg) and tibia (lower leg), joined by a deformable, simulated knee joint. The overall length of the impactor shall be 926 ± 5 mm and comply with Figure 1.

The length of the femur and tibia shall be 432 mm and 494 mm from the centre of the knee respectively.

The centre of gravity of the femur and tibia shall be 217 ± 10 mm and 233 ± 10 mm from the centre of the knee respectively.

Brackets, pulleys, etc. attached to the impactor for the purpose of launching it, may extend the dimensions shown in Figure 1, with the exception of the location of the centre of gravity.
